Easy to Grow Perennial Flowers

Perennial flowers may be expensive but are well worth the investment. Perennial flowers come back year after year and many are low maintenance, easy care plants. They are often native plants that are genetically programmed to succeed in your area. Native perennials will attract butterflies, hummingbirds, and local song birds.

Some perennials spread. Most perennials can be divided in late winter or early spring so you can start off with a small garden and expand over the years.

Perennials occasionally intimidate the new gardener. And while some perennials are a bit persnickety, the flowering plants presented below are easy to grow, tough, and attractive.

Shop around. Some places, particularly local nurseries and farm stands may offer cheaper plants than large garden centers; and can offer a greater variety than big box stores or chain garden centers.

Buying and Planting New Perennials

  • Purchase healthy looking plants with turgid stems and good foliage color. Check for signs of disease or insects, holes in the leaves, discoloration, spots or odd marks on the tops or bottoms of the leaves. When you look at the leaves, make sure there is no yellowing or brown edges.
  • Check the bottom of the pot. If you see roots poking out of the drainage hole, buy another plant.
  • You can plant perennials in spring, summer, or fall. If you plant in summer, just make sure to water enough to keep the soil moist.
  • Plant your perennials in rich, well drained soil. Add some compost to the garden in spring and sprinkle some bone meal around or in the planting hole for full, bright colored blooms. Make sure the hole that you dig is slightly larger than the root ball and fill in with compost enriched soil.
  • Water your newly planted perennial every day until the plant becomes established—that is, when the plant sprouts new leaves. Water every 5 days or so thereafter if it does not rain. The second year, you can probably water once a week.

Keep Those Perennials Coming Back

The following spring after you have planted perennials, check the garden for new growth. It is easy to mistake young plants for weeds. You can wind up pulling up last year's plants. Learn the leaf shapes of your plants so that you can recognize them early in the season.

Take photographs of the plants when they are in bloom. Step away from the garden to get an over all view. This can help you locate the plant the following spring. You can also make a simple map for reference in the spring.

When you plant your new perennial, tuck the plant tag so just a bit is sticking out of the soil. You can also make or purchase plant tags to place near the perennial. This is a simple way to locate the plants in spring.
